Description

(5) CHAIN CONVEYOR FOR ROLL MOVEMENT

The invention relates to the processing of metals by pressure and, in particular, can be used in wide strip mills for hot rolling.

A conveyor for moving coils is known, comprising two continuous chains of carts worn on idle and driven sprockets. The upper branches of the chains are the rollers of the carriages along the guides of the beams. The lower branches on the side of the idler sprocket move along the support rollers, and on the side of the drive sprocket they sag freely. Bearing carts are made with a flat top, which is caused by the need to install rolls on them in a vertical position 111..

However, during operation it is difficult to lubricate the rollers of the chain carts. Circuit-lubricating machines almost do not work. Lubrication when exposed to high temperature fade. The rollers are wedged, which leads to an increase in resistance to the movement of the chain. In addition, the conveyor requires frequent maintenance and repair.

Also known conveyor hot rolled coils containing longitudinal beams sections of I-beams with supports, support rollers installed in the supports of the longitudinal beams, drive and non-drive sprockets and chains L21.

The disadvantages of the known conveyor are as follows.

I-beams, from which longitudinal beams are made, have insufficient flexural rigidity.

Claims (2)

15 Bending in the longitudinal beams cause additional resistance to the movement of the load. The outcome of the requirement is Bars, longitudinal beams are shorter, which leads to an increase in the number of joints in the rack and the number of cross beams on which longitudinal beams are installed. All this leads to an increase in the weight of the metal structure of the conveyor, and also leads to an increase in the labor capacity of the manufacturer. In addition, the support roller casks are located between the flanges of I-beams, and the roller bearing assembly is located on the flange of the beam, which causes an increase in the distance between the roller supports and, accordingly, an increase in the bending moment in the roller. The diameter and weight of the roller axis increases. The support rollers are rigidly connected to the longitudinal beam with bolts, so it is difficult to replace the rollers during repair. A disadvantage of the known conveyor is also a great resistance to the movement of the chains, since the chains move along a common (for two chains) supporting roller. Slipping of one of the chains relative to the second chain is observed. The aim of the invention is to facilitate the conditions of service. This goal is achieved by the fact; that in a chain conveyor for moving coils containing longitudinal beams of sections of I-beams with supports, supporting rollers mounted in the supports of longitudinal beams, driving and non-driving sprockets and chains, the rollers are located above the beams, and the roller supports are made in one piece with the beams . The rollers are fixed in the supports by means of a locking connection. FIG. 1 shows the conveyor, hot rolled coils, general view; fig 2 is the same cross section; in Fig. 3 - a separate roller section of the rack (with longitudinal and transverse beams); in fig. - the design of the longitudinal beam with a common support for the rollers; in fig. 5 crosswise to the beam. The conveyor consists of drive 1 and idler 2 sprockets, drive chain k 3 and electric motor S, side guides 6. The conveyor is roller and consists of separate sections (Fig. 3). The conveyor shelf section consists of 7 longitudinal and 8 transverse beams. The longitudinal beam is made of an I-beam, to the top shelf of which a common support 10 for rollers is welded along the entire length. In the support there are nests 11 for approaching the axes. The ends of the axes of the rollers have ledges 12, with which they, with the sockets of the supports 4 11, form a locking easily-folding connection. The crossbeam 8 is made together with the uprights 13 to which the side rails of the rails are fastened. The support roller (fig. 3) consists of an axis, bearings 15 and two barrels 16. The bearing is fixed in the barrel by spring rings 17. The longitudinal beams 7 are mounted on the transverse beams 8 and are interconnected by rods 18. The longitudinal I beam is made of a high-grade I-beam rolled together with a common support for the rollers will provide an opportunity to increase the moment of resistance to bending by up to 30% compared with the known I-beam. Therefore, you can increase the length of the section and reduce the number of transverse beams and joints in the conveyor rack. Manufacturing is simplified and the number of fasteners is reduced. The height of the support is equal to half the diameter of the roller barrel, which makes it possible to place the roller above the I-beam and, therefore, reduce the width of the rack and the length of the roller. The implementation of an I-beam of long products together with a common support for the rollers and the location of the common support in the middle of the shelf allows to increase the strength of the longitudinal beam and the axis of the roller and, consequently, reduce the intensity of the conveyor. Economic efficiency is approximately equal to VL thousand rubles. Claim 1.
